摘要
土石坝是水工建筑物之一,一般由土或石料或当地材料筑成。饱和砂土地基是土石坝地基基础之一,关于其地震液化的研究也很多。通过对饱和砂土地基地震液化的产生、动力控制方程和有限元解析的介绍,对实例进行动力响应分析,并阐述加固措施。
Earth-rock dam is one of the hydraulic structures,which are generally made of soil or stone or local materials.Saturated sand ground is one of the foundations of earth-rock dams,and there are many studies on its seismic liquefaction.Through the introduction of the generation of seismic liquefaction of saturated sand foundation,dynamic control equation and finite element analysis,the dynamic response analysis of an example was carried out,and the reinforcement measures were expounded.
